What is "Double Clicking"?
Also known as switch chatter, this is a common physical failure in mechanical switches (Mouse and Keyboard). It happens when the copper leaves inside the switch bounce or corrode, sending two electrical signals for a single physical press.
How This Test Works
Human fingers generally cannot physically click faster than once every 80-100ms. If this tool detects a gap shorter than 80ms, it is flagged as a potential hardware failure (Double Click).
- Safe (Green): Normal intentional clicks.
- Fail (Red): Unintended rapid-fire clicks from a failing switch.
